Throws:

FissuresException

replaceChannelOrientation

public static ChannelId replaceChannelOrientation(ChannelId chanId,
                                                  java.lang.String orientation)

rotateGCP

public static float[][] rotateGCP(LocalSeismogramImpl x,
                                  LocalSeismogramImpl y,
                                  Location staLoc,
                                  Location evtLoc)
                           throws FissuresException,
                                  IncompatibleSeismograms

rotates the two seismograms to the great circle path transverse (X) and radial (Y). It is assumed that the two seismograms orientation are perpendicular to each other and are oriented in the east, x and north, y, directions. They must also have the same number of data points.

Throws:

FissuresException

IncompatibleSeismograms

getRadialAzimuth

public static double getRadialAzimuth(Location staLoc,
                                      Location evtLoc)

getTransverseAzimuth

public static double getTransverseAzimuth(Location staLoc,
                                          Location evtLoc)

rotate

public static float[][] rotate(LocalSeismogramImpl x,
                               LocalSeismogramImpl y,
                               double radians)
                        throws FissuresException,
                               IncompatibleSeismograms

rotates the two seismograms by the given angle. It is assumed that the two seismograms orientation are perpendicular to each other and that the sense of the rotation is from x towards y.

Throws:

IncompatibleSeismograms

FissuresException

rotate

public static void rotate(float[] x,
                          float[] y,
                          double radians)
                   throws IncompatibleSeismograms

Rotates the x and y arrays by the given angle in radians. The x and y axis are assumed to be perpendicular. Theta, in radians, is positive from x towards y, and so a rotation of PI/2 puts x into y and -y into x.

Throws:

IncompatibleSeismograms

rotate

public static void rotate(float[] x,
                          float[] y,
                          java.awt.geom.AffineTransform affine)
                   throws IncompatibleSeismograms

Performs the rotation from the given matrix. It is assumed to be a pure rotation matrix (no translation) and the translation components of the affine transform are ignored if present.

Throws:

IncompatibleSeismograms

rotate

public static void rotate(float[] x,
                          float[] y,
                          float[] z,
                          double theta,
                          double phi)
